Home Renovation Budget Calculator
Estimate the cost of your renovation based on Spanish market prices 2025-2026.
Renovating a home is one of the most significant investments a homeowner can make. Knowing a rough budget in advance allows you to plan financing, negotiate with contractors confidently and avoid unpleasant surprises. Prices vary depending on the quality of materials chosen, the geographical area and the company hired, but this calculator gives you a reference range based on updated market prices for 2025-2026.
Add the different items in your renovation — painting, flooring, bathroom, windows, electrical installation... — with the surface area in square metres or number of units. You'll instantly get an indicative minimum and maximum budget. Prices include materials and labour, but do not include VAT.

Indicative estimates based on average Spanish market prices (2025-2026). The actual budget depends on material quality, location and contractor. Always request at least 3 quotes before hiring.
How prices are calculated
The ranges reflect average construction sector prices in Spain (2025-2026), including materials and labour. The minimum price corresponds to budget finishes and the maximum to medium-high quality. Prices do not include VAT: renovations to a primary residence are taxed at the reduced rate of 10%.
How a renovation budget is estimated
The budget is built by adding up items, not by applying a single price to the total square metres. Each work chapter has its own unit of measurement: demolition, flooring, tiling and painting are measured per square metre; plumbing and electrics are usually quoted per point or per complete dwelling; and elements such as doors, windows or sanitary ware go by unit. To the sum of materials and labour you add indirect costs, which include waste management, protection of non-renovated areas, municipal permits and, if the work requires it, the technical project and site supervision. Finally VAT is applied, at 10% for home renovations meeting certain requirements and 21% for the rest.
Worked example
For an 80 m² home with a mid-range full renovation at €700/m², the bulk of the work comes to €56,000. If that scope includes a complete bathroom (about €6,000) and a kitchen (about €9,000), check that the per-square-metre price already covers them so you do not double-count. To the resulting figure you would add around 10% for contingencies, about €5,600, plus the applicable VAT. A realistic budget would therefore fall between €68,000 and €75,000 depending on finishes.
Indicative prices by item in Spain
| Item | Indicative price |
|---|---|
| Full renovation (mid-range) | 600 – 900 €/m² |
| Complete kitchen | 6.000 – 12.000 € |
| Complete bathroom | 4.000 – 8.000 € |
| Electrical installation | 40 – 70 €/m² |
| Plumbing | 40 – 80 €/m² |
| Flooring | 30 – 60 €/m² |
| Wall tiling | 30 – 50 €/m² |
| Painting | 8 – 15 €/m² |
How to interpret the budget
Treat the figure obtained as a starting range for negotiation, not a closed price. Always set aside an extra 10% to 15% for contingencies: in older properties it is common to uncover hidden problems with damp, obsolete installations or damaged floor slabs that only appear once the floor is lifted or a wall is opened up. Check too that the quote includes debris removal and permits, two items some companies leave out to present a lower figure. And be wary of offers far below the rest: in renovations, a difference of more than 25% against other quotes usually signals items not accounted for that will surface later.
